How many litres of hot water do two people need?

How much water do two people use on average?

Water use in a household of two varies with personal habits, such as how often and how long you shower and how much hot water you use. On average one person uses about 50 litres of hot water a day, which means two people need around 100 litres.

The size of water heater two people need follows from that use: an ordinary daily routine of showering, washing up and perhaps a bath. A shower uses about 9 litres a minute, so a short five-minute shower takes around 45 litres. Add the small household jobs, washing up or rinsing something by hand, and two people are soon past 100 litres a day.

But what if you sometimes shower a little longer, or take a bath regularly? Or if you have appliances that draw hot water? Then it is worth considering a larger one. Read our blog about how many litres a household of four needs as well.

Why a larger water heater is sometimes better

A 100-litre heater is enough for two people in theory, but in practice a larger one often works out better. A 150-litre heater gives you more room, certainly if you take longer showers or want to fill a bath without running out of hot water.

A larger model also prepares you for what comes. Suppose the household grows, or you start using hot water more often for a bath or for washing up. With a heater of 150, 200 or even 300 litres you can be sure you never run out.

With the energy management system you can follow what you use in real time through an app, and set the system so the water heats only when there is enough solar energy available. A smart, clean way of using energy that gets the most out of your panels.
